TYPO3 Core

Hello, i don't know why, but when i try to localize an entity, the commands run several hours until i kill the process. But why this happens? No errors nothing

        \TYPO3\CMS\Core\Core\Bootstrap::initializeBackendAuthentication();

        $this->dataHandler = GeneralUtility::makeInstance(DataHandler::class);
        $this->siteFinder = GeneralUtility::makeInstance(SiteFinder::class);

        $cmd['tx_XXXX_domain_model_product'][3379]['localize'] = 4;
        $dataHandler->start([], $cmd);
        $dataHandler->process_cmdmap();
